Answer 2

Step-by-step explanation:

$2\pi \ \times rh = 1520 {cm}^{2} \\ \pi \: {r}^{2} h = 10640 {cm}^{3} \\ \frac{\pi \: {r}^{2}h }{2\pi \: rh} = \frac{10640 {cm}^{3} }{1520 {cm}^{2} } \\ \frac{r}{2} = 7cm \\ r = 14cm \\ 2 \times \frac{22}{7} \times 14 \times h = 1520 {cm}^{2} \\ h = (1520 \div 88)cm$
